You could use rand() or srand() for it. Read the manual in google for the details.

I've got an assignment about database recovery system. I need to find an organization/enterprise and figure out its recovery system. I ask for help from someone who ever made or knew database...

Your array can't contain all the number. You'll save 2*numsegs to your array[numsegs].

fgetc returns char type but your array is int type.

Maybe that's the problem

Maybe you should change this part

char tempString1[60];
char tempString2[60];
char tempString3[60];

into


char tempString1[61];

I suppose you've made some mistake at while loop from line 39 to 50. Value of b can't fulfill the condition to end. This line made it
b = b%16;

You've done some mistake at line 14, 22, and 30.

Actually, when you declare
char TempString[60];
it means you've allocated 60 char with index from 0 to 59. Hence you can't access...

You could declare some global variable so you could exchange handle in it but you must do it carefully.

IMHO I think you don't need to make a thread for a line-counting program.

You could read the manual for every function to know why it doesn't work.
Just ask Mr. Google and Mrs. Wikipedia :p

If you really want to make an array of char without '\0' at the end of it. You could make something like this


#include<stdio.h>

int main()
{
char *insert = "abcdefgh";
char outsert[8];...

1. Do these code valid?
port=atoi(argv[2]);

I suppose atoi() isn't ANSI C
You could use this for exchange
sprintf(argv[2], "%d", port)

2.
This syntax is risky...

Thank you.

Nice to meet you guys...

'A' is a char.
"A" is a string.

String is an array of char that ends with NULL.
